Recycling is an essential pillar of a zero-waste lifestyle. It is virtually impossible in our society not to use cardboard, glass, recyclable plastics, etc. With this material already created and a part of the Earth, it is key to close the waste loop by recycling waste and creating something new rather than creating more material to be put into landfills. One contaminant in a recycling bin can ruin an entire batch of recyclable material. Make sure you know these common contaminants to make sure you are recycling properly.
